CVE-2019-16930
Zcashd in Zcash before 2.0.7-3 allows discovery of the IP address of a full node that owns a shielded address, related to mishandling of exceptions during deserialization of note plaintexts.
Does this matter?
Lower severity and a low EPSS score (1.64%). Track it; it rarely justifies an emergency change on its own.
Description
Zcashd in Zcash before 2.0.7-3 allows discovery of the IP address of a full node that owns a shielded address, related to mishandling of exceptions during deserialization of note plaintexts. This affects anyone who has disclosed their zaddr to a third party.
